At least one component comprises a liquid repellent surface layer. The liquid repellent surface (e.g. layer) may comprise a porous layer and a lubricant impregnated into pores of the porous layer; a fluoropolymer; a fluorochemical material and an organic polymeric binder; or a fluorochemical material melt additive and a thermoplastic polymeric material component. The component is typically a liquid reservoir, a liquid reservoir liner, a lid for a liquid reservoir or liner, or a combination thereof. In some embodiments, the component comprises a thermoplastic polymeric material. In some favored embodiments, the component is a removable liquid reservoir or liner. In some favored embodiments, the component is a collapsible liquid reservoir or liner. The spray application system typically further comprises a gravity-fed spray gun. Also described are spray application systems, methods of using a spray application system, as well as methods of making a component of a spray application system wherein the component has a liquid repellent surface. ## Claims ### Claim 1 (canceled) ### Claim 2 (depends on 40) The spray application system of claim 40 wherein the liquid repellent surface comprises a surface layer of a fluorochemical material. ### Claim 3 (depends on 40) The spray application system of claim 40 wherein the liquid repellent surface layer further comprises a non-fluorinated organic polymeric binder. ### Claim 4 (depends on 2) The spray application system of claim 2 wherein the fluorochemical material is a compound has the formula: (Rf-L-P)nA Rf is a fluorinated group; L is independently an organic divalent linking group; P is a catenary, divalent heteroatom-containing carbonyl moiety, such as —C(O)O—; A is a hydrocarbon moiety; and n typically ranges from 1 to 3. ### Claim 5 (depends on 4) The spray application system of claim 4 wherein L is a hydrocarbon moiety comprising 4 to 40 carbon atoms. ### Claim 6 (canceled) ### Claim 7 (depends on 4) The spray application system of claim 4 wherein Rf is CF3[CF2]3— for at least 50 wt.-% of the fluorochemical material. ### Claim at position 8 8-9.
